What else can I help you with?
Why short circuit calculation is not required for LT cables?
Lt cables has own impedance which reduce the short circuit fault level
Techniques required for increasing the input impedance?
...of what? to a house, to a breaker (to lower fault current level?), to an amplifier circuit?
What is fault level of a substation?
The maximum current that flows when there is a short circuit in the substation.CommentThis is not strictly-speaking true, as fault levels are expressed in MV.A, not in amperes, but it does allow the value of likely fault currents to be calculated.
How do you calculate rated kva of a circuit breaker?
You don't calculate the rated kV.A of a circuit breaker; it's determined by the manufacturer. It's important that a circuit breaker's rated kV.A exceeds the fault level kV.A at the point where the circuit breaker is located, otherwise it may fail to interrupt a fault current and, possibly, self destruct.

Trouble code P0463 means: Fuel Level Sensor A Circuit High Input
What is the short circuit level on 11 KV feeders of WAPDA?
The short circuit level on 11 kV feeders of WAPDA (Water and Power Development Authority) typically ranges from 10 to 25 kA, depending on factors such as the configuration of the network and the capacity of connected transformers. This level is crucial for ensuring system reliability and safety, as it determines the maximum fault current that can occur during a short circuit. Proper protection devices and system designs are implemented to handle these fault levels effectively.
Can inserting a resistor in a circuit produce an effect similar to a open circuit?
Of course it depends entirely on the ohm's resistance of the resistor. The higher the resistance, the lower the comparison to a short circuit.
What is short circuit voltage?
Short circuit voltage is the voltage that has to be applied to the primaries of a transformer, so that the nominal current flows through the secondaries, when they are shorted. This value is important, if transformer secondaries shall be used in parallel. Ideally all transformers with parallel secondaries should have the same short circuit voltage. When their short circuit voltages are different, the transformer with the lower short circuit voltage will be loaded more than their relationship of power ratings would predict. The short circuit voltage is also important in the design of a transformer, because it predicts, how much the secondary voltage will drop at nominal output current. This knowledge helps the designer to find out, how many further windings the secondary needs for a certain voltage in relation to an ideal transformer. Short circuit voltage is also known as impedance voltage.
How Elevation effect in mechanical engineering?
EQUIPMENT OUTPUT DERATION: Particular example is the Generator Set installed at 1000 meters above sea level the power output is derated due to pressure.
What is the unit substitution fault finding technique?
Unit of fault level is KA. Kilo amps
How can I use a Johnson noise calculator to determine the level of noise in a circuit?
To determine the level of noise in a circuit using a Johnson noise calculator, you need to input the resistance and temperature of the circuit into the calculator. The calculator will then provide you with the Johnson noise voltage, which represents the level of noise in the circuit.
Relation between kva and fault level?
There isn't enough information here. Available short circuit fault level can be given as a KVA value for different types of faults, but I assume the questioner is looking for a relationshiop between (transformer?) KVA and available short circuit current - If my assumption is correct, there is no direct correlation without knowing the transformer positive and zero sequence impedances. If these are known, you can assume the source impedance is infinite, and calculate the maximum short circuit current through the transformer as follows: lowside fault current for a 3 phase fault on the lowside of the transformer: lowside kV (line to line) / (1.732 x per unit positive sequence impedance x scalar to real impedance), where scalar to real impedance is equivalent to lowside kV (line to line) ^2 / base kVA. For a L-G fault, do the same with zero sequence impedance.
